Modify SortableArray List so that it implements Comparable.<> The order should be similar to the lexicographical order for Strings. Specifically, compare the elements at each position, starting with element 0. The first SortableArray List to have a smaller element at some position is the smaller one. If one of them runs out of elements before a difference is found, the one that ran out is the smaller one, just as the String "gar" is less than "gargoyle".
